Why should water be excluded from a Grignard reaction?  Since this is the case, why does just addition of a cotton ball work for our reaction setup

What reaction will occur when benzoic acid is mixed with sodium bicarbonate? (Hint: benzoic acid is an acid and sodium bicarbonate is a base...) What three products will be generated by this reaction? (You may have to look this one up...) HO. Na HO.

Consider the given reaction in which NC−NC− is the nucleophile and CH3CNCH3CN is the solvent. The reactant molecule has a structure with solid and dashed wedge bonds. A solid wedge () is used to show the bond that is above the plane of the paper, and a dashed wedge () is used to show the bond that is behind the plane of the paper. Draw the product of the following reaction:

Dangerous Paint Stripper Jessica has a summer job working for the city parks program. She has been using a cleaner called “Graffiti Gone” to remove graffiti from the bathrooms. She has to take a lot of breaks, because the chemical makes her throat burn. It also makes her feel dizzy sometimes, especially when the bathrooms don’t have very many windows. On the label, she sees that the cleaner has methylene chloride in it. She feels like she’s managing to get the work done, but she is worried about feeling dizzy. She wants to find out more about this chemical, what harm it can cause, and whether there are safer ways to do this work. Questions for following story. 1. What went right in this situation? 2. What went wrong in this situation? 3. What steps should be taken in this workplace to make sure employees are better protected and prepared the next time?

If we were to increase the temperature of an equilibrium reaction, what would you expect to see and why? The rxn is slightly exothermic.

Draw the content of the final reaction mixture. Explain your reasoning.

7) Which statement about chemical equilibrium is not true? A) The same equilibrium state can be attained starting either from the reactant or product side of the equation. B) At equilibrium, the reactant and the product concentrations show no further change with time. C) At equilibrium, the forward reaction rate equals the reverse reaction rate. D) Chemical equilibrium can only be attained by starting with reagents from the reactant side of the equation. E) At equilibrium, the reactant and product concentrations are constant.

Draw structural formulas for organic products A and B in the window below. Li Cul -Br pentane Draw only products having the organic portion of the original alkyl halide. • Draw carbon-lithium bonds using the single bond tool. If a structure has a copper-lithium bond, do not draw the lithium. • Separate products from different steps using the → sign from the drop-down menu.

Predict and complete two reactions of a compound with water. Use a single arrow to indicate that the reaction proceeds to completion and a double arrow to indicate an equilibrium. Phases (liquid, aqueous, etc.) are optional. Reaction A: H,S + H,O Reaction B: CaH, + 2H,0

What potential future problems could be involved in instructing customers of craft breweries to adopt this most recent way from the very beginning?
